<strong>Oil</strong> <strong>and</strong> <strong>Gas</strong> Development <strong>and</strong> Impacts<br />

Maintenance Procedures<br />

Production wells require ongoing maintenance, such as replacing worn or malfunctioning equipment<br />

<strong>and</strong> painting <strong>and</strong> cleaning the equipment. Periodically,oil <strong>and</strong> gas oper<strong>at</strong>ions require significant<br />

maintenance, called workovers. During a workover several tasks may be undertaken<br />

such as: repairing leaks in the casing or tubing; stimul<strong>at</strong>ing the well; perfor<strong>at</strong>ing a different section<br />

of casing to produce from a different form<strong>at</strong>ion in the well; applying corrosion-prevention<br />

compounds; <strong>and</strong> removing accumul<strong>at</strong>ed salts (scale) <strong>and</strong> paraffin from production tubing, g<strong>at</strong>hering<br />

lines, <strong>and</strong> valves.<br />

<strong>Oil</strong> <strong>and</strong> <strong>Gas</strong> Processing, Refining <strong>and</strong> Transport<strong>at</strong>ion<br />

There are a host of issues rel<strong>at</strong>ed to large oil <strong>and</strong> n<strong>at</strong>ural gas processing facilities, refineries <strong>and</strong><br />

pipelines. It is beyond the scope of this guide to go into detail on all of the issues rel<strong>at</strong>ed to oil or gas<br />

once it leaves a surface owner’s property. For more inform<strong>at</strong>ion, refer to the resources in Chapter V.<br />
